aenreU'L'rUaaL IMPLEMENT.

Be lrnown that T, ANDREW xnL'roN, a citizen of the `"United States, residing at Graetting'er, in the county of italo Alto and State of Iowa, have, r invented certain new and useful Improvementsr in Agricultural Implements; and I' do declare the following tov be full, clear, and exact description of the invention, such as will enable others skilled in the art to which 4itappertains to make and usethe same.

This invention relatesl to an improved agricultural implement of the riding typeA and `more specifically off the harrow or weeder type and oner objectot the invention is to provide an agricultural machine having a. main frame andauxiliary frames which carry earth working implements and are positioned beneath the main fra-me and supported for vertical adjustment by improved supporting means.

Another object of the'invention is to so' mount the auxiliary frames that they may be suspended by chains or other flexible sup'- po-rts and have their forward end portions connected with hanger bars which are vertically adjustable andare supportedin stir` rups which may be moved to adjust the hanger bars by means of latch levers which are further intended to serve as means for carr ino' the chains or cables. 2D

Another object of the invention isto so construct the machine 'that the vauxiliary frames which carry the earth working" implements may be capable ot a lcertain amount of" upward movement when in an opera tive position and thus permitted to pass over rocks and other obstructionsv in field without damage to the machine. p

vAnother object of lthe'`invention is to so construct` thisY machine-that the" pull exerted bythe draft horses' may be directly `applied to the auxiliary'frame andthe pull thus ex-` erted where thegreatest resistance occurs;

Anotherobject of the 'invention is to so construct this machine 'tb at' the'forward end portions of the auxiliary tramesmay'be cony. nected with hanger bars which servenot onlyl asfsup'pting means for the'forward end portions of the auxiliary'frames'but also serve as drag bars'tor transmitting movement to the main frameoi the machine when Specification of Letters Patent.

upwardly to Alift the forward ends oit the auxiliary frames at the same time thatv the chains are drawn upwardly to lift the frames out of an voperative position. f K *rfinother object of the invention is to soY constructgthis machine that it will be easy toxoperate and have a construction which vwillbe strongland durable and not liable to get out of or er or readily break. i

"Figure '4L is a"'transverse sectional view taken along" the line 4-4 of Fig. 3..

Figure 5 is'a sectional view taken along the line 5-5 of Fig., 3.

This agricultural machine is provided with a .main frame which includes a tongue 1 andy rear cross bars 2 which extendtransversely 'of the tongue at its rear end and is braced by diagonally extending bracing bars This cross bar 2 'is provided witlrdepending side arms l'having spindle extensions 5 upon whichA will be rotatably mount-` ed the supporting wheels '6 of the main frame. The drivers seat 7 -is positioned to the rearof'the cross bar 2 and tongue l and willy be connected with 'the rear end portion of the tongue'by means of'a supportingarm 8; It is to be understood of course that this main trame'may be modified in its construction and that any conventional structure of main frame of this character maybe used providing of course that the main frameincludes horizontal tongue and a cross bar at-fthe rear end of the tongue from which willextend depending side arms rigid with the cross bar and having wheel-carrying' spindles vat their lower ends. It will be furn ther understood that while the device has beenillustrated inr connection with Ya large horse-drawn machine, it could be'constructed onV a smallerscale asa hand cultivator.

` The auxiliary frames 9 which-arefvto carry the'e'arth working Vimplements extend longitudina'llyl of thefvmain frame beneath the 'side portions thereof or in other words upon opposite'sides of the vtongue land each is in the form oi" an open frame having at its forward end a ,bearingv ear l0 with which will be connected a hinge leaf 1l for fitting 13 pass.

to pivotally mount the hanger bar its rear end. A bearing' plate 16 is secured to the underface of t-he tongue 1 and serves .to pivotally mount stirrups 17 through which the forward endportions of the hanger bars form of a crank shaft having` its depending crank portion formingl the' stirrup proper Aand having its inner arrn` 18,' extending horizontally and j nirnal`ed in the bearing plate lland its outer arm bent to provide a substantiallylvertically disposed lever portion 19 having a side extension 2O which passes through an opening formedv in the forward end of a link 21. Each of these links ex- Vtend rearwardly andl is loosely connected with one side of a foot extension 22 formed upon the lower end portion of a latch lever 23. The latch levers 23 are pivotally conn I ne-ctcd with racks 24 and are provided with latch plates 25 which are slidably mounted upon the latch levers and provided with side extensions 26 so that these: latch plates may be readily moved into and out of eng-agement with the teeth of the rack. Each of the latch.` levers carries a pivotally` mounted znear 27 with which is connected a chain 23 andthe' lower ends of these chains have their lower ends connected with yokes 29 carried by the auxiliary frames. These yokesare positioned at the longitudinal centers'of the auxiliary frames and itv will be readily seen that when the latch 'levers are' swungto` draw the chains upwardlyi the auxiliary frames will be drawny upwardly.

VAt the same time, the'stirrups will `be swung upwardly and the hanger bars elevated. Therefore, the auxiliary frameswill at all times' remain substantially horizontal. When however the machine is moving' across afield and the earth 'working implements carried by the auxiliary frames strikelarge stones or other obstructions over which'they cannot pass at the normal ground-engaging position, the forward end portions of the auxiliarygframes may first swing upwardly and themachine may pass over the obstructions without injury being done to the earth working' implements. In the present illustratiom the earth working implements consist of disks 30'- whichl are rigidly mounted uponf'shafts 31 carried by the auxiliary frames "and carry prongs 32 which are to operate as rotary tooth harrows or as weed removingfprongs. These prongs willl extend in overlappingV relation asthe disks rotate and: therefore clogs of earth and weeds picked up by the prongs will be removed'. 1n order to draw the machine across a field,

Each lof these stirrups is in thev there has been provided eveners 33 which are connected with carrierbars 34;. These baiis 3e: are disposed vertically and have their lower ends connected with bearings 35 which extend forwardly from rkthe downturned end portions ofthe hanger bars. The upper ends of .these 'carrier bars 3a extend through slots formed in the end portions of a guide strip 35 which extends transversely of the tongue 1 and through a bracket 36. A pin 37 passes through the bracket 36 and guidel 35 so thatl thisg'uide strip 35 will be pivotally mounted;

W' hen the machineis in use, the draft animals are connected with the evenerslyand the pull willv be Vdirectly vapplied to `the hanger bars 13 and through the medium of these bars te the auxiliaryv frames and main frame. The latch levers will be swung` for-` wardly to bring the prongs 32 into proper engagement with the ground, and as the chine moves across a eld, the engagement of the prongs with` the ground wil-l cause rotation of the disks so that the prongs may out into theV ground and break up large lumps of earthv in case the device isv being vused as a rotary harrow or dig into the' the bowlder as-the auxiliary frames when,-

in the operative position are capable of ver-V tical movement due to the fact that `the hanger bars extend through the stirrups which are open at their upper ends and, also due to the fact that the auxiliary frames are suspended by means of chainswhich pro-v vide iiexible supports. Therefore, the auxiliary framesvcan move upwardly when the prongs engagel the bowlder or log'and the machine may safely pass over the obstruction. i/Vhen it is desired te move fromy one field to another, the latch levers will be swung downwardly and re'arwardlyandthe chains 28 will begdrawn upwardly and the stirrups swung upwardly. The auxiliary 'frames will thus be drawn upwardly out of engagement with the ground and will be re-` tained: in they inoperative position. rilherehas. thus been, provided an agrieulturalima.- chine which is effective.. in operation either as av rotaryharrow er as a weed removing cultivator. It will be further noted that an agricultural machiney has been vprovided which is very effective in operation and very easy to operate; and furtherv soconstructed that it can beleasily adjusted.v
